The current sun disklabel code uses a signed int for the sector count. When
partitions larger than 1 TB are used, the cast to a sector_t causes the
partition sizes to be invalid:
# cat /proc/paritions | grep sdan
66 112 2146435072 sdan
66 115 9223372036853660736 sdan3
66 120 9223372036853660736 sdan8
This patch switches the sector count to an unsigned int to fix this.
